Segfault on Context creation

### Solution to issue cannot be found in the documentation.

- [x] I checked the documentation.

### Issue

`mlir.ir.Context()` leads to segfault; e.g.

```
python -c "from mlir import ir; ir.Context()"
LLVM ERROR: Attempting to attach an interface to an unregistered operation builtin.unrealized_conversion_cast.
/var/folders/6k/r_fxgcx50z3gkdnckfxkfrv40000gp/T/tmpydcpwyd3: line 3: 5863 Abort trap: 6 python -c 'from mlir import ir; ir.Context()'
```

This matches the error described in https://discourse.llvm.org/t/error-when-importing-custom-dialect-python-bindings-on-windows/82946/3
